Suppose there are N worker processes defined as follows.
Develop a monitor BarrierSyn with a procedure
passBarrier() for barrier synchronization. Use the Signal
and Continue discipline. Hint: In the monitor BarrierSyn,
you may define a condition variable oktopass and use
signal_all(oktopass) primitive to wait up all delayed
processes on the condition variable.
process Worker[i = 1 to N] {
while (true) {
code to implement task i;
BarrierSyn.passBarrier();
}
}
